Prompt loss of beam ions in KSTAR plasmas

AIP Advances, 2016
For a toroidal plasma facility to realize fusion energy, researching the transport of fast ions is important not only due to its close relation to the heating and current drive efficiencies but also to determine the heat load on the plasma-facing ...

Ray Tracing Study on Top ECCD Launch in KSTAR

EPJ Web of Conferences, 2017
The current drive efficiency of electron cyclotron (EC) wave is typically low compared with other RF and neutral beam heating system in tokamak. It is known that EC current drive by outboard launch suffers from low current drive efficiency due to ...

Analysis of synchrotron radiation emitted by runaway electrons in TOKAMAKS

East European Journal of Physics, 2013
The synchrotron radiation diagnostics allows a direct observation of the runaway electron beams and an analysis of their parameters. Strong oscillations of the instantaneous curvature radii of electron orbits were a characteristic feature of recent EAST ...
